M119 Howitzer Saddle Gun Fire Finite Element Analysis

Abstract

The M119 howitzer is the current fielded 105-mm artillery weapon. It is undergoing upgrades to the fire control system in which they will be adding new components and brackets to the existing system. Finite element analysis (FEA) was performed to determine the stress contours along the side of the saddle (a subsystem of the howitzer) in regions where holes will be added for fire control brackets. The FEA results were validated by strain gauge data from live fire test and provided the needed insight for verifying the hole locations.
